Note 9. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD (typ)
Note 10. When IPGA Gain is changed, this typical value changes between 8k
and 11k
.
Note 11. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD (typ)
Note 12. When a PLL reference clock is FCK pin in PLL Slave Mode, S/(N+D) is 77dB (typ).
Note 13. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ)
